"Split toned" ... ?
You selectively desaturated ... no? You did some selective colouring with previously desaturated colours? Is that it? (The not all grey cuffs make me think... as does the part around his nose)

An interesting method, certainly not flattering to most. Male faces might still deal with this well - women might not be overly happy with it!?!? (A thought plus question to myself, this one is).

Nice picture. The pose and the perspective is quite good!!!:thumbup:
But there is one thing that comes to mind. The hand and the ear are truncated.
Except fot that I do like your pic as well. I`d like your colorstyle, it suits to the person.
